2004 R1150RS Fuel regulator

[MOONDOG59]

This is a continuation of a no start situation. Today's journey takes us to the deep, dark nether regions beneath the battery and Bowden Box, the fuel regulator. What a bear to get to. The maintenance manual illustration shows the regulator as threaded and the text doesn't state one way or the other. Is it threaded or just tight o-rings?

The pics from the MAX parts fiche and from my shop manual "infer" that it's threaded, but it is Not clear.
There are a couple of different regulators...
Go with "threaded" - even if it isn't, it should still twist to free the O-ring.
Shop manual pic attached as a Word doc., with the MAX page below. Hope this helps.

Yea, same image I got. Even somebody with small hands would have difficulty spinning it. Is the regulator the whole assembly or is it in the "case"? Ti

Item 2 by itself ... Maybe try a bit of oil to loosen up the O-ring?

Looking at the Max Parts Fische, I would not have expected any threaded features to hold it in. There is a clamping spring (05 - 13 53 1 341 694) that is installed in the fuel distributor (01 - 13 53 7 664 857) that I assumed held the pressure regulator (02 - 13 53 1 465 106) in place. Pics do not seem to have any threads. Disclaimer, I have never work on this part on my 04 R1150 RT, so no first hand knowledge.

Remove the retaining circlip
Pull the regulator out. It will be tight as the O ring is dry.
A little WD 40 helps to get things moving.
The same applies to the injectors if they are original.

The maintenance manual image shows threads so just making sure before I destroy it. I am replacing it hence the question about which part was which part.

I have rocked it and tugged at it to no avail. Guess I am going to have to get nasty with it. Stand by

Circlip ... Item #5?

Looks exactly the same as the one I did on my R850R -- and yup, it's tricky to get out. You're working against two old and dry O-rings that have swollen from over a decade of contact with gasoline.

Hold the plastic distributor carefully in place while you slowly work the regulator out of its hole. Like GSAddict mentioned, WD-40 or PB Blaster will help. Be patient and work it back and forth many times. May take you a few minutes to get it out, but that's much better than breaking the distributor.
